Mumbai: Top Indian and international personalities, film and sports icons, business tycoons, political heavyweights, celebrities and a host of others attended what was described as "a royal wedding" for the scions of two top business conglomerates - Isha Ambani and Anand Piramal - here on Wednesday.

The celebrations started in the afternoon with the traditionally attired groom, Anand, arriving on a mare at the head of a wedding procession (baraat) at the Ambani's towering Antilia residence.

The 27-storied Antilia, said to be one of the most expensive private residences in the world, itself has been decked up like a bride, and the entire stretch from the main road to the building has been decorated since the past few days with multi-hued fresh flowers, colourful lights and festoons to commemorate one of the most anticipated weddings in the country's commercial capital in recent times.

Later in the evening, the grand wedding saw the parents - industrialist Mukesh Ambani and his wife Nita, tycoons Ajay Piramal and his wife Swati - and others welcoming the high-profile celebrity guests.
